Abstract

A protective device and method of design to protect against blast and impact for use in any application in which a delicate target has to be protected. The protective device for mitigating a blast or impact frequency having a first layer having a first acoustic impedance and a second layer having a second acoustic impedance. The second acoustic impedance is different than the first acoustic impedance and the second layer is joined to the first layer. The first layer and the second layer are chosen collectively to tune the blast or impact to one or more specific tuned frequencies. In some embodiments, a third layer having a critical damping frequency that matches at least one of the one or more specific tuned frequencies is provided and the third layer is joined to the second layer.
